开始前需要了解
- Browser-Local Processing
Tool code processes selected files and entered content in your browser and does not submit them to a TOOLGRID processing endpoint.
- Device-Aware Limits
The tools report practical constraints instead of promising a universal file-size limit. Available memory, page complexity, and browser support determine what completes reliably.
- Open Without an Account
The current PDF workflows open without a subscription or account gate. Review each tool's capability notes before processing an important document.
- No Sign-Up Required
Open any tool and start working immediately. No account or email is required; selected files are not submitted to a TOOLGRID processing endpoint.
常见问题
Are my PDF files uploaded to your servers?
ToolGrid PDF tool code runs in your browser using WebAssembly and JavaScript; selected files are not submitted to a TOOLGRID processing endpoint.
Is there a file size limit for PDF tools?
There is no single reliable limit across devices. Performance depends on browser memory, page count, embedded images, fonts, encryption, and the operation you choose. Start with a copy of the file and keep the original available.
Do the tools add watermarks to my PDFs?
Never. ToolGrid PDF tools produce clean output with no watermarks, branding, or modifications beyond what you explicitly request.
Can I use these tools on mobile?
The interfaces are responsive, but large or image-heavy PDFs are more likely to exceed memory on mobile devices. For demanding jobs, a current desktop browser is the more reliable option.
Do I need to create an account?
No account is needed. All tools are immediately accessible without registration, login, or providing any personal information.
What PDF versions are supported?
ToolGrid PDF tools support PDF 1.4 and above, which covers the vast majority of PDFs created in the last 15 years.
Can I process password-protected PDFs?
No. The current browser PDF engine cannot decrypt PDFs that require a password or safely rewrite encrypted permission dictionaries. Use a trusted desktop tool with explicit PDF cryptography support, then process an unencrypted copy here.
Is my data safe with browser-based PDF tools?
Browser-local processing avoids a TOOLGRID upload path for the selected file, but it is not a blanket security guarantee. Review your browser, extensions, device security, and document sensitivity before using any web tool.
